I have seen that invoice before, with the same markings over the adresses and one where there are another layer of black marking.

The pictures also look pretty familiar - https://bitcointalk.org/index.php?topic=140099.0

Edit: As it does state that it's on it's way, I guess you cannot have your own pictures, and have used some from the net.
IOW - That the HW pictures are not your own, is not really an issue.
